Thank you all. This was helpful to me. So, to summarize all this should I say:
1. In C, we cannot define a function inside another function.
2. However, main() function is an exception as we can define another function inside a main() function. This can be called nesting of function inside main(). The inner function cannot be called from any outside function. It can be called only from main().
3. The only way to access the inner function from outside main() is by passing a function pointer of type inner function.
